Summary:

Summary File 2 contains 100-percent United States decennial
Census data, which is the information compiled from the questions
asked of all people and about every housing unit. Population items
include sex, age, race, Hispanic or Latino origin, household
relationship, and group quarters occupancy. Housing items include
occupancy status, vacancy status, and tenure (owner-occupied or
renter- occupied). The 100-percent data are presented in 36 population
tables ("PCT") and 11 housing table... (more info)

Summary File 2 contains 100-percent United States decennial
Census data, which is the information compiled from the questions
asked of all people and about every housing unit. Population items
include sex, age, race, Hispanic or Latino origin, household
relationship, and group quarters occupancy. Housing items include
occupancy status, vacancy status, and tenure (owner-occupied or
renter- occupied). The 100-percent data are presented in 36 population
tables ("PCT") and 11 housing tables ("HCT") down to the census tract
level. Each table is iterated for 250 population groups: the total
population, 132 race groups, 78 American Indian and Alaska Native
tribe categories (reflecting 39 individual tribes), and 39 Hispanic or
Latino groups. The presentation of tables for any of the 250
population groups is subject to a population threshold of 100 or more
people -- that is, if there were fewer than 100 people in a specific
population group in a specific geographic area, their population and
housing characteristics data are not available for that geographic
area.

United States Department of Commerce. Bureau of the Census. Census of Population and Housing, 2000 [United States]: Summary File 2, Advance National. ICPSR13288-v2. Ann Arbor, MI: Inter-university Consortium for Political and Social Research [distributor], 2002. http://doi.org/10.3886/ICPSR13288

The data are provided in four segments
(files) per iteration. These segments are PCT1-PCT4, PCT5-PCT19,
PCT20-PCT36, and HCT1-HCT11. The iterations are Parts 1-250, the
Geographic Header file is Part 251. The Geographic Header file is in
fixed-format ASCII and the Table files are in comma-delimited ASCII
format. The Geographic Header file has 85 variables, Segment 01 has
224 variables, Segment 02 has 240 variables, Segment 03 has 179
variables, and Segment 04 has 141 variables. When all the segments are
merged there are 849 variables.

Methodology

Data Source:

self-enumerated questionnaires

Extent of Processing: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of
disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major
statistical software formats as well as standard codebooks to accompany the data. In addition to
these procedures, ICPSR performed the following processing steps for this data collection:

Created variable labels and/or value labels.
